The multiplicity and the Wyckoff letter say how many copies of the site the group makes in one cell and on which kind of symmetry element the site sits; the 10 atoms drawn above are these sites multiplied by all 4 operations. Press Wyckoff under Colour to see the sites, and tick a symmetry element on the left to see which atoms lie on it.
How to read the label
A2B3_mP10_11_2e_3e-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol mP10, then the space-group number 11, then the Wyckoff letters occupied by each element in turn (Mo: 2e; Mo: 2e; S: 2e; S: 2e; S: 2e). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
